STM32-MAT/Target Simulink blocksets for pure simulation

Is it possible to use the Simulink blocks of the SMT32 peripherals (out of the Target Support Package - STM32 Adapter) in "pure simulations" (simulation / Debug without deploying it to the target hardware)? Or can these blocks only used for the code generation process?

Desired application:

Trigger the conversion process of the ADC with an Timer; the ADC Channel imput will be simulated with a Simulink block and the output of the ADC will be tracked with a Display (Simulink block). See sketch in attachment.
